Hi Brian,
If you were comparing the G3 Pro to the Hydra 52 and the budget allowed, I would say go with the G3 Pro because of the added "wattage".
Do you have a 220 DD? I have a client with that tank running 3 x 52's and he's not running them at full power. He's getting full coverage with this type of set-up…
Give us a call when you have some time. We'll get deep into details to see what best will suite your needs.
Thank you
